Fascinated by such mathematical elucidations of natural beauty, FSB filtered the dynamics of the Golden Section through the keyhole of the architectural hardware trade to come up with a pleasing door-handle shape. A radial grid was created in our CAD system, the technical requirements for a door handle were entered and a line was plotted through whirling rectangles with the aid of right angles and the Fibonacci sequence (0, 1, 1, 2, 3, 5, 8, 13, …). Without further ado, there appeared on the screen the aesthetic soul of a handle shape bending gently back towards the door leaf – an irrational measure of grippability of a most reasonable kind.
The rest was quite routine. Incorporating a circular grip cross-section gave life to FSB 1160, an alternative to conventional door lever handles based on the laws of Pythagoras and exuding “harmonia et symmetria”. The handle tapers from neck to tip – likewise observing the rules of the Golden Section. This reduction in width further intensifies the momentum of the natural path of the curve. The resultant design is discreet, securely grippable and geared to the user’s direction of motion.
